Interaction X Rays With Matter Flashcards
Define electric magnetic radiation
Energy that travels across empty space
What properties does EMR have
Particle like properties
What are the 4 fates of individual X ray photons
Penetration
Absorption
Scattered with energy loss
Scattered without energy loss
Define penetration.
Photon penetrates matter without interacting with it
Define absorption
Photon interacts it with the matter and is completely absorbed by depositing all its energy into the matter
Define scattered
Photon interacts with the matter and is scattered from its original direction
What is attenuation
Attempt to numerically describe the collective fates of large number of photons as they interact with matter
What are the two components of attenuation
Scatter and absorption
What are the two important attenuation process
Compton or modified scatter
Photoelectric absorption
What is elastic scatter
Involves scattering of photons without loss of energy at very low x ray energies
What is inelastic scatter - important
Scattering of photons with energy loss
What is energy gap within the atom
Difference in binding energies between shells
